[BUG] Vanilla Marlin for Einsy Rambo not working in MK404 sim.

[3d-gussner]

Describe the bug
Got vanilla Marlin for Einsy Rambo kind of working and it can be flashed on a physical printer.
Trying to load the same hex file in MK404 doesn't do anything.

To Reproduce
Steps to reproduce the behavior:

1. Compile https://github.com/3d-gussner/Marlin/tree/MK3s_2.0.x
2. Copy \.pio\build\rambo\firmware.hex to your MK404 build folder
3. Start MK404 /build/MK404 -f firmware.hex
4. MK404 starts but no output on LCD on terminal

Expected behavior
It would behave like the real Einsy board.

Desktop (please complete the following information):

• Hyper-V VM
• OS: [Ubuntu]
• Version [18.04.1]

Have you tried running with -n (aka --no-hacks)? This is necessary because the TIMSK tweak we need to get the firmware to boot has the opposite effect on stock Marlin.

Sorry didn't find this issue #117 Thanks

Solved

Not a problem :)

Maybe when I figure out #75 this workaround can go away and both work without it

Good news (also @leptun ) - --no-hacks is no longer necessary for Marlin thanks to closing #75.
